Hey what do I do with the main ground from the battery to the chasis to the tranny....can I cut it right at the chasis to tranny???or can i get rid the whole cable...let me know thanks

 

I guess you could cut it at the chassis, as long as it stays contacted to the chassis securely, alternatively you could ditch the ugly old cable and make a new one out of 4 gauge cable, or even 2 gauge if you want it really chunky.
